Volumetric flow rate or mass flow rate?

As with most flowmeter selection processes the choice of volumetric or mass is decided by just a couple of criteria. Here’s how: The first step is defining the fluid type i.e. liquid, gas, steam etc. Once you’ve decided your application is liquid, the next most important criteria is cost. Whilst it’s true that some processes … Read more

Five secrets to selecting the optimum ultrasonic flowmeter

Flow meters based on the ultrasonic principle can be excellent solutions to flow measurement problems.  Our CEO Charles Wemyss exposes five secrets to consider when selecting the best Ultrasonic flow meter.
